Almost all k40 laser cutters have a 300 x 200 mm work area that is sufficient for cutting and engraving smaller objects. However, there are some variants with larger work areas that are perfect for working on bigger projects.

Some K40 laser cutters come with safety features such as an emergency stop button that instantly shuts down the machine if a dangerous situation arises. These safety features help ensure the safety of the operator and reduce the risk of fire accidents.

The best K40 lasers are also equipped with a water flow sensor that triggers the laser only when water flows through the laser tube, preventing the machine from overheating. This sensor is particularly useful if you plan to run the laser for extended periods of time, as it enhances the machine’s cooling abilities and prolongs its lifespan.

Aside from this, some K40 lasers also feature a rotary axis, which is useful for engraving cylindrical workpieces like cups and bottles. Moreover, some K40 laser cutters can be upgraded with more powerful control boards, air assist, and air purifiers to improve their performance.
